Title: Binary balanced transmitting system having error correcting function
Inventor: KIKKAI NORIAKI
IPC: H04L1/00
Filed: 1986-01-20
Abstract: PURPOSE:To maintain the error correcting capacity of a Hamming code and, at the same time, to make error correction possible, by constituting an error correcting code which is controlled so as to produce the mark rate balancing property in the block of an error inspecting bit and mark balance adding bit. CONSTITUTION:After an information sequence is distributed to four sequences by means of a serial-parallel conversion section 1, error inspecting bits c1-c4 are implemented to each sequence by operation. Eight-sequence signals are combined at a parallel/serial conversion section 2 and converted into optical signals by an electrooptic converter 3, and then, the optical signals are sent to an optical fiber cable. Received optical signals are converted into electric signals by a photoelectric converter 4. The electric signals are first distributed to 8-sequence signals by a serial/ parallel conversion section 5 and block synchronism is secured to the sequences. Collation of an inspection pattern with a received inspection pattern is performed by an inspection pattern collating section 7 and a syndrome is found by means of a syndrome generating section 8. Wrong bits in the information sequence are corrected at an error correcting section 9 and the original information sequence is restored by a parallel/serial conversion section 10.

Title: Refresh circuit in semiconductor memory device
Inventor: TANABE AKIRA
IPC: G11C11/406
Filed: 1991-01-28
Abstract: PURPOSE:To reduce the power consumption and to increase the speed in a system by performing the refreshment only when the signal in the refresh address generating means detects the electric charge of the cell for the flag and the electric charge is reduced lowered than the fixed level. CONSTITUTION:When the access is performed for the specified word line WL, WL goes to H and the voltage for node CELL H as electric charge is stored in a capacitor C. At this time, when this voltage in the cell for flag is read by the refresh decoding signal, H is outputted to the self-refresh control circuit and the refreshment to the word line is not performed. When the capacitor C is discharged and becomes lower than the fixed voltage after the lapse of time, the output in OUT becomes L, L is outputted to the control circuit and the refreshment to the word line is performed. Thus, the reducing of the power consumption by not performing the refreshment when the electric charge is left in the memory cell and the speed of the system is increased by setting the refresh time to zero.

Title: Boron steel with superior machinability and hot forgeability
Inventor: OOTANI SABUROU
IPC: C22C38/14
Filed: 1978-01-28
Abstract: PURPOSE: To prevent deterioration of the machinability and hot forgeability of a boron steel as well as to ensure the hardenability with a small amt. of B by reducing the N content of the steel with superior hardenability as low as possible to lessen the amt. of Ti used to fix N.  
     CONSTITUTION: A mechine structural steel contg. N<0.007%, Ti; 3×[N]W 0.035%, Si; 0.04W1.5% and B; 0.0005W0.002%. By adding the slight amt. of B to steel, the hardenability is enhanced, and the addn. of S improves the machinability. In case the N content is high, the hardening characteristics of B are deteriorated, so Ti is added to fix N as TiN. Since a large amt. of Ti deteriorates the machinability, the N content is controlled to below 0.007%. Accordingly, the amt. of Ti added  can be reduced, the machinability enhanced with S is not deteriorated, the B content can be lowered, and the forgeability is held, resulting in the desired superior  machine structural steel.

IPC: C21D9/573
Filed: 1983-01-21
Abstract: PURPOSE:To obtain a thin steel plate excellent in flatness by uniformly cooling the thin steel plate, in performing continuous annealing, by winding the thin steel plate around cooling rolls cooled by a liquid while blowing non-oxidative gas between the thin steel plate and the cooling rolls. CONSTITUTION:For example, a thin steel plate 1 obtained by cold rolling an Al- killed hot rolled steel plate formed from a molten state in a converter is heated to a predetermined temp. in a continuous annealing furnace and, after gradual cooling, the cooled one is wound around two cooling rolls 3, 3 through which hot water is passed and subsequently cooled in air. In this case, non-oxidative gases 4, 4 each containing 2% or more of H2 or/and He are blown to the gap of the thin steel plate 1 and the rolls 3 at the inlet side of the rolls to uniformly cool the thin steel plate. By this method, even if slight faulty contact exists between the cooling rolls and the thin steel plate, the thin steel plate can be uniformly cooled by the cooling gas and, as a result, the thin steel plate good in flatness can be obtained.

IPC: F24F7/08
Filed: 1984-01-20
Abstract: PURPOSE:To contrive to eliminate the air resistance due to a heat exchange element and consequently to enable to use a ventilating fan under increased air flow rate and at the same time to reduce the power consumption by a structure wherein a bypass unit, which is interchangeable with the heat exchange element of an air conditioning ventilating fan, is provided in a main body so as to remove the heat exchange element during the in-between season such as spring, autumn and the like. CONSTITUTION:A bypass unit 9 consisting of a right square prism shaped box can partition into a delivery passage 8 and a discharge passage 7 by erecting a partition plate 14, which has been lying, at its center after a heat exchange element 108 is removed. Whe discharge blades 15 and delivery blades 16 are rotated by a motor 17, the indoor air flows in a course indicated with the arrows D and D' in the direction running from D to D', while the outdoor air in the direction running from C to C'. In this case, both the indoor and outdoor airs do not mix with each other by being partitioned by the partition plate 14. The mounting of the heat exchange element 108 is done by removing a cover 9a at one side of the bypass unit 9 and inserting the element. As a result, only the ventilation can be efficiently performed during the in-between season such as spring and autumn, without performing heat exchange.

Abstract: PURPOSE:To eliminate wiring disconnection in the neighborhood of an SiO2 isolating region in the event of a reduced region area caused by excessive abrasion by a method wherein a part of the collector compensation diffused region is caused not to overlap the isolating region. CONSTITUTION:A part of a collector compensation diffused region 29 is caused to sufficiently extend inward beyond an isolating region 24 and is shaped into a laid down U shape, when a master pattern is used for the purpose of keeping the part extending inward of the U shape may not overlap the region 24. In this setup, island region area reduced thanks to excessive abrasion during the photolithographic process prior to compensation diffusion does not cause a dent etched in the isolating region during the process of forming an electrode outlet in the part occupying the part beyond the inside brim of the isolating region. Accordingly, by leading a collector electrode wiring layer out of the collector compensation region into the area outside the island region, disconnections in the wiring layer and the like can be eliminated.
